I have a question regarding /etc/hosts for CentOS 6 x64. I already have
a hostname set on my server, however there are 10 additional IP aliases
assigned to the box, one which I plan to use as a mail server. The mail
server will be serving mail for a completely different domain (different
then the default hostname of my box). My question is this: If I take one
of my additional IP addresses and bind it to postfix for mail, do I also
have to specify the remote IP and mail server hostname in /etc/hosts?
For example my hosts looks something like this
Can I add?
Is this even necessary?
